摘　　要：持久性有机污染物(POPs)通常种类繁多,结构复杂,以痕量或超痕量的方式存在于环境介质与生物体中,具有较高的生物毒性和环境危害性.近年来,被动采样技术在环境监测领域及POPs污染水平评价方面应用广泛,发展迅速,根据不同的吸附材料可将被动采样器划分不同的装置类型.本文综述了大气持久性有机污染物被动采样技术(passive atmospheric sampling, PAS)的基本原理,总结了半透膜被动采样器(SPMD-PAS)、聚氨酯泡沫塑料被动采样器(PUF-PAS)、聚合物涂层玻璃被动采样器(POG-PAS)、高分子树脂聚合物被动采样器(XAD-PAS)这几种常见的大气被动采样器的组成结构、采样原理、特点及应用情况,分析了大气被动采样技术研究领域的动态,提出了被动采样技术目前亟需要关注的问题和存在的主要困难,并展望了该领域的研究前景.Persistent organic pollutants(POPs)have a great variety with complex structures.Usually,in the environment medium and organism,POPs are present at trace or ultra-trace concentrations,which poses the high biological toxicity and environmental harmfulness.In recent years,passive sampling technology has been widely used and developed rapidly in the field of environmental monitoring and POPs pollution level assessment.The different types of passive samplers can be divided by various adsorption materials.This paper gives an overview of the basic principle of passive sampling techniques(PAS)for POPs in the atmosphere,and summarizes the structure,sampling principle,characteristics and application of several passive samplers,including semi-permeable membrane device passive sampler(SPMD-PAS),polyurethane foam passive sampler(PUF-PAS),polymer-coated glass passive sampler(POG-PAS)and resin-based passive sampler(XAD-PAS).The development research of PAS is analyzed,and the problems and difficulties of passive sampling technology is also pointed out.Finally,this study prospected the research direction and prospect in this field.
